I'm looking for a story, I can't remember if it's Sam/Dean or Jared/Jensen. If it was Sam/Dean, they were unrelated. It was an AU where Sam/Jared left his abusive ex with his daughter and they met Dean/Jensen at a diner and then he found them with a broken down car and invited them to stay with him. Dean/Jensen was a hunter, but he had been injured during a hunt where Bobby died so he took over the salvage yard. It was set during winter/Christmas time.
